@ -28,19 +28,21 @@ I try to integrate every datapoint from Batriums BMS to fill Victrons registers.
- transfer of most alarms (instead of only voltage low alarm)
- number of cells balancing
- time to empty or full
- capacity used
- daily stats Ah and kWh charged, discharged (calculated)
- correct transmitting of CVL (fixed with Batrium version 2.17.40.0 or downgrade to 2.17.27)
- capacity used and total Ah discharged
- daily stats like kWh charged, discharged (calculated)
- time since last full charge
- correct transmitting of CVL (Stock implementation fixed with Batrium version 2.17.40.0 or downgrade to 2.17.27)
## What is not working, needs improvement
- capacity to full or to empty is not transmitted by Batrium (transmission of 0x00111900 is missing against documentation)
- Ah used and kWh charged and discharged is calcualated by script (see above)
- Ah, kWh charged and discharged is calcualated by script (see above)
- Capacity of battery must be entered into script batrium.py (see above)
- dbus script is started by rc.local which gets executed last, so all mppts and multiplus' showing temporarily "BMS missing" and need to be cleared after (re-)boot of Venus OS
- include calculation of State Of Health, based on Ah discharge and SoC State after full charge, becuase Batrium does not have
### Victrons datapoints
This script will emulate one of Victrons own BMS, therefore are many registers to fill, but I dont know how to fill all.
For example time to last full, where set timestamp or what mean average Ah discharged.
For example what means average Ah discharged. I implemented datapoints to my best knowledge and it is working for me.
